Subtractive Design : A Novel Approach to Heatsink Improvement

posted Jun 7, 2018, 9:53 PM by Songyi Han

Typical Heatsink design includes base and fin thickness, fin height, and fin gap optimization. In situations where material cost or mass of the heatsink are also a design priority further optimization with respect to mass removal can be significant.

This paper discusses a method to further improve a heatsink topology by the systematic removal of heatsink mass where the Thermal BottleNeck (BN) Number was found to be lowest.
